Zea/Z7, whom it may concern/r" Beit known that I, HALLE E. WILLIS, of Lebanon; in the county of Grafton and State of New Ham shire, havefinvented certain new and usefu Iinprovements in Electric Inducti'on Batteries, of which the following is a vibrations of the'circuit-brealier may be di .1 thebattery-cell which generates the curre'nt.*

ADOtherob ect is to provide a more con1- pact and acces'siblegarrangement for mount- In carrying out these objects I rnount the 1 circuit breaker or interrupter so that the viall vas*desciibed and claimed in the following specification and illustrated in'the drawings.

It is well known that the rapid vibrations of the circuit-breaker produce a note which is very insistent and annoying. .It is articularly objectionable in a therapeutica dein an abnormally sensitive condition, so that they are more strongly affected-and disturbed toa greater degree by continued sounds of this character. Usually the circuit-breakers in such devices are mounted permit 'the circuit-breakers making their unyielding in any otherdirection and are rigthe base,by which thelatter is supported.

circuit-breaker and in the spring are directly transmitted and carried to the base ofthe apparatus,'which, being usually a fiat'board, is a powerful resonator whichigreatly intensifies the sound produced. by these vibrations. It is the aim of my invention-to eliminate the reinforcement of this sound by the resonant that caused by the circuit-breaker itself and will therefore be of much less intensity than when reinforced by the vibrations of the base. I accomplish this by securing the circuitbreaker. 9 upon the end of a spring 10,, which is formedeof as manyspiral coils as can conveniently be employed, and the opposite end of which is secured to "a holder 11. teris connected electrically to and supported coil; the latter being conirocted with one end offthe pri nary winding. Thus-the circuitbreakeris supported yieldinglyfat the endol ingly up and do Wn'and in any "directionfwhab have found that when the circuit-br'e' keris vice, as the. nerves of invalids. are frequently upon springs which yield only in one line to Thereby the soundevibrations set up in the time mounted the noise; pro'dudedf liyery rupter or breaker is represented by 9 and is l necessary vibrations; but such springs are idly secured either to the induction-coil or to brat-ions transmitted therefrom to the supporting-base of'the battery, which acts as a i resonator, will be absorbed-and their 'intene,

In the form shown in Fig. 3 the holder 11 is connected with the flange 12 by a number of arms 13, whichare resilient and yield lat erally but not in the direction of their lengths. With this form of the device the vibrations must be absorbed whollyby the spring 10. In Figs. 5 and 6, however, I provide an additional sound-absorbing contrivance which consists of the springs 14, used as substitutes for the arms 13 in connecting the holder 11 to the flange 12 of the coil. As may be readily seen, these springs support the holder itself yieldingly, and so act still further to absorb and diminish the intensity of the vibrations transmitted from the circuit-breaker.

As previously stated, the currentennet ing device consists of a battery-cell 4. In order that this may be accessible, I'inclose it removably in a casing 15, which has a detachable cover-16 at one end. Mounted in the cover 16' is a stud 17, insulated therefrom by a bushing 18 and having on its outer end a clam -nut19. This stud is connected with the e edtrode 20-of the battery cell by a wire 2i. In the opposite end of the casing is fixed a stud 22, having a clamp-nut 23. This stud is connected with the other electrode through the body of the casing 15 and the outer shell of the cell 4, which makes contact with the casing. These studs 17 and 22 are set into notches in the ends of the supports 5 and 6 and are clamped therein by the nuts 19 and 23. Thus the cell is not only supported by the members 5 and 6, but the latter serve as leads to conduct the current therefrom to the coil. As they rise from the base the cell is thereby supported in a position where it can be easily removed when it becomes exhausted and needs renewing, and the casing enables the cell to be rotected' from injury. This construction 0 the casin and cell also enables cells of any size to mounted in the battery, for the casin is large enough to take the largest cell of t e requiredflsort which makes a cldse fit therein, and of course cells of smaller size may be inserted. The metallic shell of the cell restin against the casing makes a contact therewit and with the stud 22, while the flexible connection 21 enables the cell, whatever its size'or form of carbon may be, to be connectedwith the stud 17. I claim.
